Docker Compose

Docker Compose configurations for local development and testing.

Edge Gateways

Located at docker/compose/docker-compose.yml. Builds the gateway image from the repository root using the Dockerfile at src/Voltimax.Edge.Gateway.Service/Dockerfile.

Usage

docker compose -f docker/compose/docker-compose.yml up --build

Gateways

Runs three gateway instances in parallel for testing multi-gateway scenarios.

Container	Host port	Gateway ID
voltimax-gateway-1	18081	gateway-001
voltimax-gateway-2	18082	gateway-002
voltimax-gateway-3	18083	gateway-003

ServiceBus is enabled, connecting to the local emulator on host.docker.internal:34861. Restart policy is no.

Feature Flags

All optional features are disabled by default:

Flag	Default
Features__EnableConfigurationUpdates	false
Features__EnableApplyStrategy	false
Features__EnableSendControlSignals	false
Features__EnableChangeMonitoring	false

Set any of these to true via the environment section in the compose file to enable them.

Volumes

Each gateway uses two named volumes:

• *-state → /var/lib/voltimax-edge — persistent gateway state
• *-config → /etc/voltimax-edge — gateway configuration

EVerest Demo

Located at docker/compose/everest/docker-compose.yml. Runs the full EVerest open-source EV charging stack in software-in-the-loop (SIL) simulation mode, useful for testing OCPP integration end-to-end without physical hardware.

Usage

docker compose -f docker/compose/everest/docker-compose.yml up

Services

Container	Host port	Description
everest-mqtt-server	2727	Mosquitto MQTT broker for EVerest inter-module communication
everest-manager	8849	EVerest core manager running SIL simulation with OCPP 2.0.1 support
everest-nodered	1880	Node-RED simulation UI for controlling virtual charging sessions

Simulation UI

Open http://localhost:1880/ui to access the Node-RED dashboard. From there you can simulate plugging in an EV, starting/stopping charging sessions, and observing OCPP message flows.

Configuration

Image versions and resource limits are configured in docker/compose/everest/.env:

Variable	Default	Description
TAG	2025.10.0-single-phase	EVerest Docker image tag
EVEREST_MANAGER_CPUS	1.0	CPU limit for the manager container
EVEREST_MANAGER_MEMORY	1024mb	Memory limit for the manager container
